This game is probably my favorite in the Metroid Series. It’s a perfect example of SNES-level graphics on a small handheld. This is the most story-driven installment of all Metroid 2D games. Be ready to be lost for hours and experience a huge adrenaline boost once you finally figure out what you need to do or when you finish that impossible boss. Oh, and in this Metroid there are situations where there is no way you can win, and you have to run. Very hard.
